Page 1 of 1 To underline the performance credentials of the new Austin Healey 100, two mildly modified examples were entered in the 1953 edition of the 24 Hours of Le Mans. In a field full of specifically prepared and often very exotic racing cars the two Austin Healeys finished a commendable 12th and 14th overall.

Following up on the Le Mans success, Donald Healey offered the same modifications on regular production models as the 'Le Mans' package. This was a separate bolt-on kit that could be ordered through Austin Healey dealers. It featured larger carburettors, a cold-air intake airbox, a high-lift camshaft, stronger valve springs and a revised distributor.

When Austin Healey launched the subtly modified 'BN2' evolution of the 100 in 1955, the Le Mans package was incorporated in the separate 100M model. This featured the same engine modifications that brought it up to 110 bhp but also had distinguishing exterior cues. These included a louvred engine cover, a leather strap to hold the cover down and 100M badging.

Between 1955 and 1956, it is believed Austin Healey built just 640 examples of the 100M, while a further 519 100s, mostly BN1s were fitted with the Le Mans kit. The 100M was phased out when the six-cylinder engined 100/6 entered production in 1956. Today, the 100M ranks as one of the most sought-after versions of the early Austin Healeys. Page 1 of 1
